Direct DNA damage
TYPE OF DNA DAMAGE
Thymine dimer; Cyclobutyl dimer; Thymine dimers; Thymine dimerization; Direct DNA damage; Cyclobutane pyrimidine dimer; Pyridimine dimer; Cyclobutane thymine dimerization; Pyrimidine dimers; Cytosine dimer
Direct DNA damage can occur when DNA directly absorbs a UVB photon, or for numerous other reasons. UVB light causes thymine base pairs next to each other in genetic sequences to bond together into pyrimidine dimers, a disruption in the strand, which reproductive enzymes cannot copy.
